一：開始學習圖形化程序設計
1 >>> import turtle #導入turtle 模塊 2 >>> turtle.showturtle() #顯示箭頭 3 >>> turtle.write("python") #寫字符串 4 >>> turtle.forward(300) #前進 300 像素 5 >>> turtle.color("red") #畫筆顏色改為red 6 >>> turtle.left(90) #箭頭左轉 90 度 7 >>> turtle.forward(300) 8 >>> turtle.goto(0,50) #去坐標（0,50） 9 >>> turtle.goto(0,0) 10 >>> turtle.penup() #抬筆。這樣，路徑就不會畫出來 11 >>> turtle.goto(0,300) 12 >>> turtle.pendown() #下筆。這樣，路徑就會畫出來 13 >>> turtle.circle(100) #畫圓
二：繪制奧運五環標記
1 import turtle 2 3 turtle.width(10) 4 5 turtle.color("blue") 6 turtle.circle(50) 7 8 turtle.penup() 9 turtle.goto(120,0) 10 turtle.color("black") 11 turtle.pendown() 12 turtle.circle(50) 13 14 turtle.penup() 15 turtle.goto(240,0) 16 turtle.color("red") 17 turtle.pendown() 18 turtle.circle(50) 19 20 turtle.penup() 21 turtle.goto(60,-50) 22 turtle.color("yellow") 23 turtle.pendown() 24 turtle.circle(50) 25 26 turtle.penup() 27 turtle.goto(180,-50) 28 turtle.color("green") 29 turtle.pendown() 30 turtle.circle(50)
